WINDOW CONSTRUCTION Carl J. Wagner,'Sturgis, Mich.

Application January 30, 1950, Serial No. 141,233

3 Claims. (01. 160-371) The invention relates to window constructions more particularly designed for use on trailers but applicable to other uses, and of that construction comprising a stationary screen-holding frame mounted in the opening through the wall and a ventilator sash hingedly secured to said frame. With such constructions the ventilator sash when closed forms sealing engagement with the frame and, as the screen is mounted in a plane inside of the outer face of the wall, it is to a certain extent out of the path of rain when the ventilator is opened. However as the stationary frame extends to and overlaps the outer face of the wall, there is a tendency for rain water collecting on said face to flow over the said frame to the screen and to drip inside the enclosure.

It is the object of the invention to obtain a construction in which the water thus collecting on the frame is directed to the outside, and to this end the invention consists in the construction as hereinafter set forth.

In the drawings:

Fig. 1 is a vertical section through the stationary frame showing the sash in elevation in engagement therewith and in the closed position;

Fig. 2 is a perspective view of a portion of the stationary frame;

Fig. 3 is a front elevation thereof;

Fig. 4 is a horizontal section on line 55, Fig. 1;

Fig. 5 is a cross section through one of the rails of the stationary frame; and

Fig. 6 is a similar view of a slightly modified construction.

A is a stationary window frame preferably formed of rails of a cross section having a portion A for overlapping the outer face of the wall surrounding the window opening therein, an inwardly extending portion A a portion A in an inner plane parallel to the portion A and a return bend portion A to which the screen B is attached. The portion A is preferably of a slightly concavo-convex form so that its outer margin will be pressed against the wall to form a sealing joint therewith. The frame A is secured in position by any suitable means but as shown is attached to an inner stationary frame C formed of rails of similar cross section, which overlaps the inner face of the wall D, the two frames being clamped to the Wall by screws D. F is the ventilator sash of any suitable construction connected to the frame A by a hinge F extending along one edge thereof.

With the construction as thus far described if the ventilator is open during a rain storm, water may flow from the outer face of the wall D over the rail A inward to the screen B and eventually drip inside of the enclosure or between the inner and outer frames A and C. No escape is provided for the water so collecting and if the wall D is formed of wood such wetting may cause it to rot.

As above stated it is the object of the invention to avoid such a result which is accomplished as follows. The rails of the frame A are modified in cross section so as to have in addition to the return bend a similar return bend A outside of the plane of the portion A Such a cross section can be formed as shown in Fig. 6 by formin the return bend A two-ply with an extension thereof forming the portion A On the other hand it may be formed as shown in Fig. 7 by extruding the rail with the portions A and A integral extensions of the portions A With either construction a trough or channel will surround the outer face of the portion A of the frame which will interrupt the fiow of any water over said frame to the screen B. Consequently, all water collecting on the outer face of the frame A will be directed downward to the lower rail of said frame and if the ventilator sash is still open it will drain off of said rail outside of the frame. It may happen that if the ventilator is open at the beginning of a rain storm and is then closed that water collecting on the frame A before such closure will collect on the bottom rail and will be held from escape by the sealin strip F. I therefore provide drainage channels for the lower rail preferably by indenting the convex portion A at one or more points as indicated at G. This will form a break in the sealing of the strip F permitting all water collecting on the rail to drain downward therefrom. Thus my improved construction of frame A will very effectively prevent the draining of water therefrom inside the enclosure.

What I claim as my invention is:

1. A window screen comprising a frame formed of like rails, each of a cross section including a portion extending in the general plane of the frame, and a pair of open return bend portions extending from the inner margin of the aforesaid portion on opposite sides thereof and generally parallel thereto, a screen fabric secured to one of said return bend portions and extending across the frame, the other return bend portion forming a channel extending around the frame, which channel opens outward with respect to the center of the frame.

2. The construction as in claim 1 in which the first mentioned portion of each rail is extended 3 4 obliquely of the plane of the frame and outward REFERENCES CITED from the center thereof on the side having said The following references are of racord in the channel, said obliquely extendin portion terfile of this patent: minating in a further outwardly extending portion generally in a plane parallel vto that of said 5 UNITED STATES PATENTS first mentioned portion.
